RMC35 commutation and incremental encoder solution

Transcription

1 Data sheet RMC35D01_06 Issue 6, 26 th March 2018 RMC35 commutation and incremental encoder solution The RMC35 is designed for use in motor feedback applications requiring both, B, Z incremental and U, V, W signals. Robust non-contact Onxis TM sensor technology provides ultimate long term reliability and with simple installation costs of ownership are minimal. Installation is simplified with a range of magnetic actuators and mounting options for the encoder. simple one time zero position programming then removes the need for careful adjustment of the encoder. Resolutions are available from 64 to 2,048 pulses per revolution (256 to 8,192 counts per revolution with 4 evaluation). U,V,W commutation signals are simultaneously output with 1 to 8 pole pairs (2 to 16 poles). Incremental resolution from 256 to 8,192 cpr Simple installation and setup U, V, W commutation signals with up to 16 poles (±24 m output drive) Industry standard incremental outputs (RS422) Operating speed to 30,000 rpm Compact - 35 mm diameter body Non-contact, frictionless design Low inertia

Install the magnetic actuator Use glue to fix the magnetic actuator to the shaft (recommended LOCTITE 648 or LOCTITE 2701). ctuator should protrude by 7 mm. 2. Install the flange with the encoder module on the mounting surface Screw the flange to the mounting surface using 2 screws (not provided). 3. Turn the power on Plug in the mating connector and turn on the power 4. Zero the UVW signals Move the motor to the required zero UVW position.
